France’s Sunology has unveiled a new residential energy storage solution called Storey. The system features modular battery units, each offering 500 W of nominal power and 2,200 Wh of storage capacity, designed to enhance solar self-consumption at home.
Up to four Storey modules can be combined to deliver a total storage capacity of 8,800 Wh and a power output of 2,000 W, adjustable in 1 W increments. Each module comes with its own built-in inverter, allowing for flexible and scalable installation.
Sunology claims an efficiency of up to 90% and offers a 15-year warranty covering up to 7,500 charge cycles. The system is priced at an introductory rate of €1,390 (including VAT).
Designed for both single-phase and three-phase systems, Storey is compatible with all brands of solar inverters. Installation is simple: for rooftop solar systems, the device connects directly to the home’s electrical panel. For homes using plug-and-play solar kits, Storey can be plugged into a standard power outlet, enabling it to store and reinject solar energy into the home at optimal times.
According to Sunology, the Storey system is designed to detect storage opportunities in under two seconds, allowing it to “capture every last kilowatt-hour of solar energy before it’s sent back to the grid.” “In the absence of a public energy service, we develop public utility products,” said Vincent Arrouet, co-founder of Sunology, in an interview with pv magazine France.
Storey is integrated with Sunology’s energy management platform, providing real-time data accessible remotely via a mobile app. It can also be paired with other Sunology monitoring and measurement devices to increase autonomy, including by factoring in weather forecasts to anticipate changes in solar production.
In the event of a power outage, household appliances can be plugged directly into Storey’s built-in outlet. If the system is connected to the electrical panel, it can continue to supply power to the home temporarily, depending on the remaining battery charge and real-time electricity consumption.
